No crime in Whitney Houston death: police

Beverly Hills police say they have concluded Whitney Houston's death investigation and found no signs that a crime occurred.

Lieutenant Mark Rosen said on Wednesday the determination was made after reviewing the Grammy-winning singer's full autopsy report, which attributed her death to accidental drowning. Coroner's officials ruled heart disease and cocaine use also contributed to the 48-year-old singer's death.

Houston died in a bathtub of the Beverly Hilton Hotel on February 11 on the eve of the Grammy Awards. She had been planning a comeback, including a starring role in the remake of the film Sparkle, which is due for release later this year.

Police have repeatedly said they have found no signs of foul play in Houston's death.
